Patent CA-2246838-C (CA)
Inventor: WEBER DALE A
IPC: H01R12/72
Filed: 1998-09-09
Granted: 2002-07-02
Abstract: A card edge type electrical connector including dual-beam ground contacts each having splayed pre-loaded tips and a realignment twist enabling a plurality of such contacts to be gang inserted into the insulator housing of the connector. To adjust the pitch of the pre-loaded tips, a predetermined twist is added to the bottom of the contacts during the stamping operation which re-aligns the tips with the correct contact receiving apertures. The re-alignment twist disappears once the contact(s) are fully seated in the insulator housing, thus allowing the pre-loaded tips to reach their ultimate position within the insulator housing relative other adjacent contacts.

Abstract: A head gate for use in controlling access of livestock to feed exposed at an open end of an elongated agricultural storage bag of the type formed of tubular flexible sheet plastic. The head gate includes a framework having a central portion which extends across in front of the open end and is provided with a number of openings sized to permit the livestock to reach through and feed from a face of compacted feed within the bag, the framework being mounted on skids to allow the head gate to be shoved towards the open end of the bag. Sheet plastic storage rolls are mounted on the framework and have a drive system to rotate the rolls relative to the framework for gathering the sheet material which had formed the bag and becomes excess as the feed recedes from the open end. The head gate allows for use of the feed directly from the bag with little labour involved while maintaining the feed clean and preventing wastage. After the stored food of the bag is completely consumed the sheet plastic of the bag which has been maintained in a neatly stored condition can be easily removed for disposal.

Patent CA-2273490-C (CA)
Inventor: ST LOUIS ROBERT MAURICE
IPC: D06F58/04
Filed: 1999-05-27
Granted: 2004-11-02
Abstract: There is disclosed a clothes dryer having a rear end head with axially spaced apart apertures through which air may enter into the dryer drum through a diffuser wall mounted to the inside of the drum end head.    The apertures in the end head have an air flow deflection shield integrally formed therewith. The air flow deflection shield extends radially across the apertures in the end head, is recessed from the rear end head and is spaced from the diffuser wall. Advantage is found with the use of such an air flow deflection shield because it permits for the apertures in the rear head to be of sufficient size to permit satisfactory air flow into the dryer drum while deflecting the air away from potential warm spots generated through and on the surface of the diffuser wall that would otherwise be in direct immediate air flow impingement with the apertures in the end head.

Title: A method for regulating fluid pressure
Inventor: HENNEL MAIK
IPC: G05D16/20
Filed: 1999-07-15
Granted: 2005-11-01
Abstract: Specified is a method for regulating the pressure of a fluid, moved through a pipe system with at least one consumer by a pressure generator, driven with an electric motor. In order to ensure a sufficient supply for all consumers on a continuous basis, the motor speed for adjusting the pressure in the pipe system (1) is regulated by way of a controller (9). At least one control curve reflecting the fluid pressure in the pipe system (1) in dependence on the amount of the fluid flowing through or the flow speed of the fluid is impressed into the controller. The control curve extends with a uniform curvature between a predetermined pressure minimum and a predetermined pressure maximum, such that in the direction of increasing pressure, it is located above a straight line connecting the points of minimum pressure and maximum pressure and is at the greatest distance from this straight line in the center region between the two points.  The controller (9) is supplied continuously with an electrical variable as actual value, which is proportional to the amount of fluid flowing through or the flow speed of the fluid. If the actual value deviates from the desired pressure value, specified according to the corresponding control curve (R), the motor speed is adjusted so as to compensate for this.

Title: Low power rectifier circuit
Inventor: CANFIELD LYLE DEAN
IPC: H02M7/21
Filed: 1998-09-11
Granted: 2006-11-14
Abstract: A low power switched rectifier circuit is realized using P-MOS and N-MOS FET  switches that are turned ON/OFF at just the right time by a detector and inverter circuit (which form an integral part of the rectifier circuit) to rectify an incoming ac signal in a highly efficient manner. Parasitic diodes and transistors that form an integral part of the FET circuitry respond to and rectify the incoming signal during start up, i.e., when no supply voltage is yet present, thereby providing sufficient operating voltage for the FET switches to begin to perform their intended rectifying function. In the absence of an incoming ac signal, i.e., during the time between biphasic pulses, the rectifier circuit is biased with an extremely small static bias current but in the presence of an incoming ac signal, at a time when the positive and negative phases of the incoming signal are to be connected to positive and negative supply lines, a much larger dynamic bias current is automatically triggered.

Title: A network management system using a distributed namespace
Inventor: PARK JOONHO
IPC: G06F13/00
Filed: 2000-05-04
Granted: 2006-07-11
Abstract: A method and apparatus are disclosed for remotely managing network elements in a distributed computing system. The distributed computing system utilizes a software entity, such as an operating system, to manage the location of, and communication with, distributed resources in the distributed computing system.  A network manager and/or SNMP agents can interact with distributed elements to obtain desired management information independent of the location of the distributed elements. Thus, master agents can communicate with managed network nodes without adhering to the intricate requirements of the SMUX or DPI protocols. SNMP MIBs are implemented as hierarchical file systems, comprised of a tree of file-like objects, that may be accessed through a namespace. The SNMP MIB namespace allows the network manager, master agent and SNMP agents to access each resource, including SNMP MIBs, in a uniform, file-oriented manner. The SNMP MIB namespace of each network node managed by a master agent can be mounted into the namespace of the master agent to create a distributed MIB namespace. The MIB of each managed node is mounted to the MIB namespace of the master agent and appropriate connections through the distributed network are established by the operating system or another software entity.

Title: Linear actuator
Inventor: NEFF EDWARD A
IPC: G01B7/00
Filed: 2000-03-16
Granted: 2001-07-31
Abstract: A linear actuator includes a plurality of magnetic plates and a ferrite core with a conductive cover which are mounted on the actuator body to generate a permanent magnetic field. The linear actuator also includes a metal bobbin which has an outer surface and which is formed with an aperture that defines an inner surface for the bobbin. Further, the bobbin is formed with a gap which extends along its length and which intersects the bobbin from its inner to its outer surface. An insulating insert is placed in the gap. Finally, a winding is wrapped around the outer surface of the bobbin to form an electromagnetic coil, and the coil on the bobbin is slidingly mounted on the actuator to receive the ferrite core through the bobbin's aperture.  Electrical current can then be selectively applied to the winding to interact with the permanent magnetic field and thereby cause reciprocating motion of the coil. Due to the gap in the bobbin, an induced current which would otherwise hinder the desired reciprocating motion of the coil does not form on the outer surface of the bobbin. Due to the conductive cover, the response time of the coil to the applied current is reduced. In this manner, precise, high speed reciprocating motion in the linear actuator of the present invention is achieved.
